目的　评价血管内支架移植物置入术治疗StanfordB型主动脉夹层的安全性和有效性。方法　 10名主动脉夹层患者 ,均在全麻下进行移植物置入术治疗 ,4例置入TALENT内支架移植物 ,6例置入国产内支架移植物。结果　 2例未能有效封堵动脉破裂口 ,其中 1例治疗后 12h因动脉破裂死亡。 1例移植物部分遮盖左锁骨下动脉 ,但无上肢进行性缺血加重 ,余 7例动脉夹层及假腔均较好封堵。术后 1周 ,9例行CTA检查 ,除 1例夹层未得到封堵外 ,其余 8例内支架移植物均无移位 ,假腔均缩小 ,真腔均扩大。随访 8例 ( 2～ 3 8个月 ) ,均无症状再发。结论　内支架移植物置入术可有效治疗StanfordB型主动脉夹层 ;严格选择适应证可提高治疗的安全性和有效性 Objective To evaluate the safety and efficacy of endovascular stent graft in the treatment of Stanford type B aortic dissection. Methods Totally 10 patients with aortic dissection were treated with transplanta- tion under general anesthesia. TALENT stent was implanted in 4 cases and domestic stent-graft in 6 cases. Results 2 cases did not block the arterial rupture effectively, of which 1 case died of arterial rupture 12h after treatment. One case of graft partially covered the left subclavian artery, but no upper limb ischemia, more than 7 cases of dissection and false lumen were better occlusion. One week after operation, CTA examination was performed in 9 cases. Except for one case, the dissection was not blocked, and the remaining 8 cases did not shift within the stent graft. The foci were reduced and the true cavities were enlarged. Follow-up 8 cases (2 ~ 38 months), no recurrence of symptoms. Conclusion Stent grafting can effectively treat Stanford type B aortic dissection. Strict selection of indications can improve the safety and efficacy of the treatment
